Material reservations over-supplied with EWM

Hi,

We're using material reservations to trigger movement of goods from an EWM sloc.

A reservation is created (MB21), and then a pick list (MB26) - this creates a delivery in ERP which is distributed to EWM.

This issue we have is, until the EWM delivery is processed and the message is sent back to ERP, it is possible to create further pick lists and therefore deliveries.

So its possible to over supply against a reservation.

The person managing the reservations has no way to know whether or not a reservation is currently being picked by the EWM warehouse.

Is this a gap in the reservation process?

Any hints or tips appreciated.

Regards

Guy

    Hi,

    as much as I agree with Jürgen, I simply say that there is no answer to this question. Because I do not think that working with MB21 and MB26 was ever build and intended to work with a warehouse management system, without regards to WM or EWM. It is simply not meant to be used in an EWM environment. There are enough other ways, with much more and better features, so why bother?

    Hi Guy

    I have the same issue. Have you already solved it?

    I found the BADI LE_SHP_GN_DLV_CREATE. Maybe you can develop such check in this implementation. But i still hope for a better solution.

    Kind Regards,
    Mario

      In step 2 - I go to MIGO - Goods Issue - enter reservation number and post -> System creates an Outbound Delivery and gets distributed to EWM, hence this is not actually posting a Goods Issue but just an Outbound Delivery is getting created here. Actual picking and Goods issue is carried out in EWM (step 3)

      Now if we go back to step 2 and repeat the steps before step 3, system creates multiple Outbound Delivery for same reservation
